請看下面一道題:
—I was riding along the street and all of a sudden, a car cut in and knocked me down.
—You cannot be____careful in the street.
A. much B. very C. so D. too
分析:該題考查的是“cannot...too...”結構的用法。答案為D。題意為:
——我在馬路上騎車,突然一輛汽車超車,撞了我。
——在馬路上(騎車),你越小心越好。
“cannot...too...”結構是中學英語課本中的一個重要句型。該結構表示“無論怎么……也不算過分”“越……越好”“要格外……”“應該特別……”等意義。表示此意義的句型結構有下列幾種:
1. cannot+be+too+形容詞/副詞
We cannot be too careful in doing experiments.
我們做實驗越仔細越好。
I cannot thank you too much.
我無論怎么樣感謝你也不過分。
2. cannot+over-動詞或cannot+be+over+形容詞
We cannot overemphasize the importance of learning a foreign language.
我們無論怎么強調學外語的重要性也不過分。
We cannot be over vigilant.
我們應該特別警惕。
3.cannot+動詞+too much
We cannot praise him too much.
我們無論怎樣贊揚他也不算過分。
He is very reliable. You can't trust him too much.
他很可靠,是最值得你信賴不過的。
4.cannot+動詞+形容詞/副詞+enough
含not的結構也可被含never, hardly, scarcely等否定詞的結構取代。例如:
You can never be strong enough.
身體越健康越好。
Drinking water can never be pure enough.
飲用水越純越好。
5.cannot+動詞+too many+可數名詞或cannot+動詞+too much+不可數名詞
It is wrong to think that one cannot bear too many children.
認為一個人孩子生得愈多愈好是錯誤的。
I think it right that one cannot learn too much knowledge.
我認為一個人的知識愈多愈好。
6.It is impossible to...too...=cannot...too...
It is impossible to emphasize this point too much.
要特別強調這一點。
與cannot...too...相似的句型結構主要有:
1.cannot help+doing:該結構意為“禁不住做……”“忍不住干……”,指“身不由己地去做某事”。例如:
We could not help thinking when we saw the Great Wall in China.
看到中國的長城,我們不禁浮想聯翩。
I couldn't help crying when I heard the bad news.
當我聽到那不幸的信息,我不禁大哭起來。
類似結構:“cannot help but do sth.”表示“不得不、忍不住”。例如:
We could not help but walk from dawn to dusk.
我們不得不從黎明走到黃昏。
I couldn't help but cry.
我忍不住哭了起來。
2.cannot but do sth.:該結構表示“不得不……”。例如:
I cannot but admire his courage.
我不得不欽佩他的勇氣。
I couldn't but laugh on reading such a funny joke.
讀到如此滑稽的笑話,我忍不住笑了。
注意:①在這個句式里,cannot后省略了do anything。例如:
He cannot but agree.
他不得不同意。
②can but do sth.表示“只得……”。例如:
The boy made an apology to his teacher, so the teacher could but give up the idea of punishing him.
那男孩向老師道了歉,老師只得打消懲罚他的念頭。
③類似這一結構的“cannot choose but do sth.”也表示“不得不……、只得……”。例如:
It rained hard, so they couldn't choose but stay at home.
雨下得很大,他們只得待在家里。
